Topics including (but not limited to)....

  • Rising power needs

  •  

    Advanced cooling

  •  

     

     

     

       Latest & Greatest New Tech

  • How compute is used

  • Efficient computing & explaining stuff

  •   We argue about it all!

Radio Free HPC (RFHPC) started in 2012 and, after a short break of 193 months, has returned to the airwaves (cyber waves?) with co-hosts Dan Olds, Henry Newman, and Shahin Khan.

The podcast covers a wide range of topics but is particularly focused on data center technology and challenges. These include high performance computing, power and cooling, new technology, and, really, whatever the hell they want to talk about.

 

Quick FAQ


"Why are you just covering HPC? There's this new thing called AI, have you heard of it?"

Yeah, we've heard of it and we do cover it. To us, HPC is a broad term used to refer to a very broad group of apps/workloads that have common characteristics.

  1. They are computationally intense
  2. Time to solution and quality of solution are critical
  3. The output is important enough to justify investment in high-end clusters and associated hardware/software

AI meets all of the criteria above just like bioscience, aerospace, weather prediction, and several other domains. In fact, AI is or will soon be folded into the workflows of nearly every 'traditional' HPC and enterprise application over time. This is going to put a lot of pressure on data centers and we'll be talking about how to deal with it.

 

"Was the old version of Radio Free HPC popular? I've never heard of it..."

Yes, it rose from obscurity to being mildly popular and, at times, entertaining. At our peak, we had as many as 16 sustained listeners and as many as 19 theoretical max listeners.

 

"I listened to the old show a couple of times and liked the arguing. Will there be more of that in this reboot?"

Yes, in fact we expect as much as 29% more arguing and a significant increase in the number of personal insults per episode.

 

"How often will this thing come out and how do I find out about it?"

We used to try to do weekly shows but failed due to other commitments, travel, etc. And there were just weeks when nothing important happened. But to answer your question, could be every couple of weeks, could be once a month, or we could record a marathon 8-10 hour single episode. Depends on what's happening and our mood.

We're getting together our RSS feeds and such but in the short term we'll be publicizing the episodes through the RFHPC X account and our individual social media accounts.

 

Ok, enough questions. If you want to learn more about the show and hosts, check out the "About" page.

Latest Episode

  • Episode 93: Trip Report on Fall 2015 HPC Conferences

    By admin | September 30, 2015 |

    In this podcast, the Radio Free HPC team goes over a Trip Report from Rich Brueckner, who’s been on the road for the past month at a series of HPC conferences:
    HPC User Forum in Broomfiled, CO. The event featured two full days of talks. Here we discuss a couple of standouts that you can watch on insideHPC:

    • Processing 1 Exabyte per Day for the SKA Radio Telescope. Peter Braam from Cambridge University presented this talk in the Disruptive Technologies session. “The Square Kilometre Array is an international effort to investigate and develop technologies which will enable us to build an enormous radio astronomy telescope with a million square meters of collecting area.”
    • ExaNeSt Technology: Targeting Exascale in 2018. Peter Hopton from Iceotope presented this talk at the HPC User Forum. “ExaNeSt will develop, evaluate, and prototype the physical platform and architectural solution for a unified Communication and Storage Interconnect and the physical rack and environmental structures required to deliver European Exascale Systems. The consortium brings technology, skills, and knowledge across the entire value chain from computing IP to packaging and system deployment; and from operating systems, storage, and communication to HPC with big data management, algorithms, applications, and frameworks. Building on a decade of advanced R&D, ExaNeSt will deliver the solution that can support exascale deployment in the follow-up industrial commercialization phases.”
    • User Agency Panel Discussion on the NSCI Initiative. In this video (with transcript) from the 2015 HPC User Forum in Broomfield, Bob Sorenson from IDC moderates a User Agency panel discussion on the NSCI initiative. “You all have seen that usable statement inside the NSCI, and we are all about trying to figure out how to make usable machines. That is a key critical component as far, as we’re concerned. But the thing that I think we’re really seeing, we talked about the fact that a single thread performance is not increasing, and so what we’re doing is we’re simply increasing the parallelism and then the physics limitations, if you will, of how you cool and distribute power among the parts that are there. That really is leading to a paradigm shift from something that’s based on how fast you can crunch the numbers to how fast you can feed the chips with data. It’s really that paradigm shift, I think, more than anything else that’s really going to change the way that we have to do our computing.”

    PBS Works User Group. Job schedulers like PBS Works are key to keeping supercomputers running efficiently. Notable talks included:

    • HPC Across the Enterprise: How HPC Transforms the Corporate IT Ecosystem. Thomas Leung from the GE Global Research Center presented this talk at the PBS Works User Group. “The commercial world uses significant HPC resources for simulation and product design. An increasing number of HPC systems are deployed in the commercial space and their scale is getting larger and larger. These advanced systems push limits in every aspect of Enterprise IT. Accommodating such systems within the enterprise is a challenge, and there have been many recent changes to enterprise IT infrastructures and architectures resulting from the need to support HPC.”
    • Video: HPC Technology Panel at the PBS Works User Group. Rich Brueckner from insideHPC moderated this panel discussion on current trends in HPC. “President Obama’s Executive Order establishing the National Strategic Computing Initiative (NSCI) will set the stage for a new chapter in leadership computing for the United States. In this panel discussion, thought leaders from leading supercomputing vendors share their perspectives on current HPC trends and the way forward.”

    HPC Advisory Council Spain Conference. This day-long event in Barcelona featured a set of great talks, but here we discuss two notable presentations:

    • Communication Frameworks for HPC and Big Data. DK Panda from Ohio State University presented this talk at the HPC Advisory Council Spain Conference. “Dr. Panda and his research group members have been doing extensive research on modern networking technologies including InfiniBand and 10-40GE/iWARP. His research group is currently collaborating with National Laboratories and leading InfiniBand and 10-40GE/iWARP companies on designing various subsystems of next generation high-end systems.”
    • The Road to Exascale. Rich Graham from Mellanox looks at how interconnects are evolving to get us to the next grand challenge of supercomputing performance.

    LAD’15 Lustre Administrators and Developers Conference.

    • On the Role of Flash in Large-Scale Storage Systems. Nathan Rutman presented this talk. “So why is a spinning disk company talking about Flash? Last year, Seagate acquired Avago LSI’s flash division. We now have an array of flash-based storage. So I have nothing against Flash. This presentation is really on: Where does Flash make sense? I also have a personal agenda because I hate the term “Burst Buffer.” Everyone says “Burst Buffer” instead of saying “Flash.” It drives me crazy. So I’m going to explain what a Burst Buffer is and what it is not.”
